Tincturing Black Walnut

Black Walnut (Juglans nigra) trees are all around here. This time of year they are thumping on roofs, smashing into cars, and sending the squirrels into a frenzy. I was first introduced to Black Walnut as a medicine over 15 years ago while in herb school, though it wasn’t until we moved onto our little homestead, and had outdoor animals to take care of, that I really got to know it.

Black Walnut is traditionally used as an anthelmintic (That’s your vocabulary word of the day. Use it the next time you are talking to your vet or doctor about worms and they’ll think you are super smart! ) That basically means that it works by expelling parasitic worms from the body.

Animals that spend most of their lives out doors (in our case, our farm dog and our chickens) are super prone to getting worms. I’ve talked about my use of Black Walnut with Suki and heart worm (see the comment section of that post), but I also use Black Walnut as a dewormer for our chickens. Twice a year, in the spring and late summer, when the weather is humid and muggy, I give them a Black Walnut preventative in their water (60 drops in a gallon of water) for two weeks. If I ever notice those classic symptoms of a wormy chicken (sluggish, droopy wings, decrease in laying), I will give them another week of it. It works wonderfully!

Black walnut tincture can cost $10-$15 an ounce in the store…. I can make a quart of it (32 ounces) for about $10. That’s about .31 cents an ounce!

So, how do you do it? It’s easy!

Here’s what you need:

Black Walnuts (I used about 12 to make a quart of tincture) You can harvest them this time of year. It’s easiest to grab them off the ground after they have fallen, because they grow pretty high up in the trees.

Alcohol (I like to use 100 proof vodka, but any alcohol that is 80 to 100 proof, or 40-50% alcohol is fine. Since my chickens aren’t picky about the taste of their tinctures, I just use the cheep stuff. This 1.75L bottle cost me $18)

A large jar (I’m using a 1/2 gallon mason jar)

Sharp knife

Wax paper

Gloves (though you can see, mine are mysteriously absent from this picture. Oh, yeah. I wasn’t wearing any.)

The state of your black walnuts is important. You want them nice and green. A black spot like this on the outside:

will look like this inside. Ewwwww! Though the chickens might not mind tinctured worms, I do!

This is what you want your walnuts to look like when you cut off the hull (or outer layer).

Cut the hull off of the walnuts and put the hulls in your jar. You will see the black walnut start to darken before your eyes! Seriously! It starts oxidizing immediately!!

I begin pouring the alcohol into the jar as I’m cutting the hulls. This keeps them from oxidizing so rapidly in the air, and puts all the good medicine in the alcohol.

So, the gloves. Yeah. It’s a good idea to wear gloves while you are cutting Black Walnuts as they can stain really badly. I forgot to pick any up at the store, so I just went for it. I think, from all the Black Walnut juice that I soaked up through my skin, I can safely say that I am now free of worms!

By the end of the cutting process the color of the alcohol had already changed dramatically, as had my fingers.

Lovely!

Once you cut the hulls, put them in the jar and cover them with the alcohol, you want to put the top on the jar. A layer of wax paper goes in between the glass and the lid. This keeps the alcohol from reacting with the metal.

You will also want to label your tincture!! Always label!! ‘Cause you might just forget what you put in there and what a waste it would be to have to throw it all out because you didn’t label it. On my labels, I always put the name of the plant, along with the percentage of alcohol, and when it will be ready to strain. (Sometimes, on you might see things on tincture bottles like 1:2 or 1:5…. that is the scientific method of tincturing and it means amount of herb:amount of alcohol or menstrum used. We’re not doing that here. We’re keeping it simple.)

Put your tincture in a shady place indoors and shake it gently for the next two weeks. Here is mine, happily resting on the kitchen counter. (Yes, those are many bottles of home made hard apple/peach cider that you see in the background!! You are very observant!)

About 15 minutes after taking the above picture, Leif asked if he could be in one of the pictures with the Black Walnut. Check out the color difference already!!

And my hands…… My fingers are about 10 shades darker as I type this!!

After letting the tincture sit for 2 weeks, you can strain the hulls out. I use muslin/cheese cloth to get all the little bits out of the fluid. Save your tincture in a clean, labeled jar (don’t forget that layer of wax paper) and store in a cool, dark place. You can bottle it up in little dropper jars for easy use.

See, wasn’t that easy???

(The happy, worm-free ladies say ‘hello!’)

Oh, and unlike many of the chemical dewormers for chickens that are on the market today, you can still eat the eggs of your chickens while they are taking Black Walnut tincture!!

Yes, like you said, you can eat the meat inside the black walnut. The are a bit more bitter than the traditional English walnut, but some people love the taste. I have a relative that makes black walnut syrup and cakes every year.

I can’t wait to make this for my girls. I never like using chemicals to kill worms. Great article. I have a question. Can you use it for dogs? My dogs catch rabbits all the time and rabbits are loaded with worms.

It is good to know there is a positive use for this tree. Sadly, it is also a powerfully toxic substance to most vegetables and at least some trees. I’ve lost a garden and several fruit trees because I didn’t know. Also, wondering if anyone has an easy solution to the blackening. It is incredibly difficult to get off. Thanks!

Instead of vodka to soak the nut hulls in, do you know if if vinegar would also work?
Is there a ratio of hulls to vodka that should be used?
Do you wash the walnut hulls before putting them in the jars for preparation?

I’ve never used it that way, but chemically, it should work. I believe Vinegar will extract the juglone from the black walnut and that is the main parasiticide component in black walnut hulls. As far as what ratio….. often when using fresh herbs, herbalists will try to get a 1:1 or 1:2 ratio (meaning 1 part (grams) of herb per 2 parts (mL) liquid. But, again, I’ve never made this with vinegar, so it may take some googling to see if you can find a recipe. And yes, I will give the hulls a scrub in water, but nothing crazy, just like you’d clean a potato before baking.
